You've both _got_ to be kidding!  Do you have nothing else to do?

I definitely don't have time to mess with another instance of even a
system I do use, let alone a whole other kind of system than the kinds I
already use, virtual or otherwise, just to get a different version of a
portable compiler to use.  That's *insanity*.  I sure as heck don't want
to spend good money on more hardware just for this kind of thing.

(maybe such suggestions are not as insane as suggesting I purchase
another machine and also purchase and run Windoze on it too, but they're
still pretty insane ideas to me)

It's enough of a time waster using additional machines (virtual and
real) just to test stuff I have to test, let alone adding more machines
just to test software that will already run on an existing machine.

Maybe if I had a personal sysadmin assistant (and a spare bag of
cash)....  Anyone want to volunteer to be my "slave" for such tasks?

I may soon be able to trivially install different versions of GCC
simultaneously which are that new, or even newer, on an existing system
I use.  The trick here is not also wasting time trying to build
something from scratch that I would only do a one-off test with.  If my
already-in-use packaging system adds the newer GCC versions which won't
interfere with the production version I need, then I can trivially
install newer GCC packages just for these kinds of tests.
